Hello, I am new to this. I am TTC. My last period was 5-11-08 and I had sex on 5-25-08 the same day I was to OV. It is now 10dpo and I have sore nipples and abdominal cramping. I haven't has any light bleeding or anything, just headaches and nausea. Could I be pregnant if I had sex on my OV date? %-)
